O Yes O No O since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1 . O Since at least one of the probability values is greater than I or less than 0. O Since the sum of the probabilities is not equal to I. O Since the sum of the probabilities is equal to 1 O Since the probabilities lie inclusively between 0 and 1 02017 Hawkes Learning Type here to search

Explanation / Answer

A dicrete probability distribution is where the sum of the probabilities = 1. Here the sum of probabilities 0.49 + 0.47 + 0.46 = 1.42 i s> 1, therefore

No. Since the sum of the probabilities is not equal to 1.
